Reverb

Altiverb is a sampled acoustics processor that offers realistic one-, two- and four-channel sampled acoustics of real halls, cathedrals, bathrooms — and virtually any acoustic environment. Included in the release are dozens of presets ranging from the Amsterdam Concertgebouw to the back of a Ford Transit van, all of these can browsed online and downloaded from www.audioease.com/IR .

Altiverb provides mono-to-mono, mono-to-stereo, stereo-to-stereo, mono-to-quad, and stereo-to-quad effects, making it ideal for surround reverb and ambience applications. All processing is done in real time.

Altiverb is a sampled acoustics processor that offers realistic one-, two- and four-channel sampled acoustics of real halls, cathedrals, bathrooms — and virtually any acoustic environment. Included in the release are dozens of presets ranging from the Amsterdam Concertgebouw to the back of a Ford Transit van, all of these can browsed online and downloaded from www.audioease.com/IR .

Altiverb provides mono-to-mono, mono-to-stereo, stereo-to-stereo, mono-to-quad, and stereo-to-quad effects, making it ideal for surround reverb and ambience applications. All processing is done in real time.

An Altiverb preset is called an 'impulse response', which is created by firing a starter pistol or by playing a sine wave sweep from a speaker in an auditorium, church, or other acoustic space. The resulting reverberation decay is recorded as a digital audio file. Using a process called deconvolution, the dry source signal is then extracted from the audio file, leaving behind the exact acoustic fingerprint of the space. The impulse response file is then placed in a folder, to make it appear as a preset inside the Altiverb plug-in, where it can then be applied to any audio signal as real-time reverb. The result is a true reproduction of the sound of the acoustic space. Unlike reverbs of the past, which attempt to synthesize decay characteristics, Altiverb captures the actual acoustics of a particular environment.

Altiverb includes the Impulse Response Pre-Processor software, which allows users to sample any acoustic space, hardware reverb, or other source to create their own Altiverb presets. In addition, users can take photographs of the place they are acoustically sampling, and place JPG images in the same folder. Altiverb then displays the JPGs as a slideshow when the preset is chosen in the plug-in. In addition, these pictures can show mic positions and other details of the sampled space.

fixed: IR not found errors. The extension matching is case sensitive. .L and .R extension are found now.
fixed: Similar did not work on User IRs. Now it compares to Audio Ease IRs only.
fixed: crash in VST version at session load when IRs can’t be found.
fixed: VST version did not show the additional channel volume controls in XL version.
fixed: Drag and Drop in VST (mainly Cubase and Nuendo) did not work.
improved: mono-mono instance of Altiverb can load any IR (also multi channel).
improved: loading of host plug-in presets is faster.
fixed: an issue in Pro Tools when track automated "Automation Preset Parms" aka Snapshots where used in conjunction with other parameters.
fixed: the installer would crash when it finds strange characters.
fixed: the interface for offline processing in Digital Performer is on the wrong position .
fixed: Pre delay could reset itself.
fixed: drag import of AIFF files would not work correctly in 64 bits versions.
fixed: hang when drag import split files.
fixed: pre delay of notes gets changed when tempo changes exists in a song.
several smaller fixes and improvements.

Known issues:

If you close a VST song while the Altiverb browser is open (and a category is selected) you may experience a crash. This is after song save though, it should be harmless. The same goes for host application quit, as that closes the song as well.
In some situations the IR Browser window does not open in Digital Performer.

An algorithmic synthetic reverb layer that is tightly tailored to the impulse response provides a type of brightness that an EQ could never boost from a real world room.

News

Keep your IR library up to date from within Altiverb. You can go into Altiverb's news tab, see what's new and proceed to download and install without restarting, all from within Altiverb 7.

Similar

The room does work, but it is not quite the perfect one yet? Hit Similar and Altiverb will suggest similar sounding alternatives to the chosen impulse response.

TDM simplified

In Altiverb 7 XL, the TDM chip management can be done from within Altiverb, using one handy pop-up menu. This feature does away with the long list of Altiverbs in the TDM plug-in popup. On top of that Altiverb 7 XL allows the loading of all IR types (down to mono in / mono out) into a stereo to quad instance of Altiverb.

Total Recall Automation

Everything, including the impulse response choice is automatable in Altiverb 7. This means that you do not have to jump through hoops to fully automate Altiverb 7. And while there are still single-click snapshots, you do not need them to automate Altiverb. You can even read which IR is chosen in the automation curve.

Drag and drop

Just drop any audio onto Altiverb 7 to use it as an impulse response: sweep recordings, several type claps or bangs, or any kind of experimental audio like crashing cars or piano chords. The drag and drop IR feature includes new make-up curves that allows the making of decent IRs using a handheld portable radio, or even slates.

Chaos

Dial in a bit of chaotic modulation and not every hit will sound identical in the reverb. As a bonus tonal material will be dispersed which means that slightly out of tune notes will be covered up in the reverb tail.

Interactive EQ curve

To operate the equalizers you can still use the familiar turning knobs. But Altiverb 7 adds an interactive equalizer curve that allows you to set al four bands including the widths of the parametric ones.

And More...

Altiverb supports 64 bits. It has a new reverb gate, and straightforward pre-delay and attack parameters. Times can be set in note values locked to your song's tempo, and you have 10 times as much space in the stage positioner.

The RTAS version has been fixed to work with optimal performance in Mac OS X 10.5.3 and Pro Tools 7.4.2. Earlier there was the need to exclude some processor cores from RTAS processing, the playback engine can now be set to the number of processor cores available.

[PT TDM] The TDM version has a fix to make reloading a session with several Altiverbs active reliable. Data traffic to and from the DSPs could be hampered during load of a session, especially with an Expansion Chassis (ethernet or Magma) is connected. The fix makes the traffic reliable, albeit on a chassis somewhat slower.

[PT ]The RTAS version has been made better compatible for exchanges between PC and Mac, and between HD and LE systems. A session with a TDM version inserted will now open an RTAS instance automatically when transported to an LE system.

Important note for VST users using automation in VST sessions, as well as all Pyramix users:
Due to necessary improvements in the handling of VST automation data we have been unable to maintain automation in sessions made with Altiverb VST version 6.1.2 or before. Typically: gain knobs left at 0 dB in 6.1.2 or lower appear as +13.2 dB in Altiverb VST 6.2.0. This only goes for automation data. regular saved settings appear fine. Pyramix useres will see this in the loading of regular settings from sessions as well.
